WORK POSITION - ADJUSTMENTS
During operation, the tractor linkage must always be in the free floating position and the transport lock of the 3-
point frame (B) must be unlocked (lock V, photo 1, page 17). Raking height of the GA 4511 GM is correct
when tines lightly sweep the ground in front of the machine with tine arms kept horizontal to the ground.
Before carrying out any operation such as maintenance or adjustment on the
machine, stop the tractor engine, remove ignition key and wait for the rotor to stop
before leaving the tractor.
Bogie Axle Height Adjustment :
- Clear the wheels off the ground by lifting the machine by means of the tractor 3-point hitch.
- Remove linchpin (E) and pull wheel axles (T) away from the machine so that pins (P) are freed from their holes
(photos 6 and 7).
- Position the wheel axles (T) at desired height and insert pin (P) in the corresponding hole of vertical sector (S)
(photo 7).
- Secure wheel axles by putting linchpins (E) back into place.
NOTE : After each wheel height adjustment, make sure that the pin (P) is fully engaged in its housing on the vertical
sector (photo 7).
IMPORTANT : For certain conditions of work, in particular when raking straw, it may be advantageous to increase
the distance between tines and the ground. In order to do this, the boogie axles (T) must be secured
in place using the lower fixation hole provided in the wheel column support axles (see photo 6).
Guards :
Guards are lifted and lowered by a hydraulic cylinder (H).
Guards must always be lowered during operation.
Hydraulic cylinder (H) has a latch (A), locking guards (P) vertically in place when in transport (photo 8).
To lower guards (P) into the work position, pull cord (K) to free latch (A) (photo 8), then open hydraulic cylinder (H)
until guards (P) are completely lowered (photo 10).
Check if rebound stop (L) is engaged under guard support (C) (photo 9).
Swath screen adjustment :
- Sideways adjustment : With the guards lowered, keep opening up hydraulic cylinder (H) which will automatically
swing swath screen (G) into the work position. Sideways adjustment is then easily carried out in accordance with
crop density.
- Vertical adjustment : 5 positions (E) can be selected (photo 10). As a rule, the screen (G) should be fixed in
the centre. The other positions are to be used only if necessary :
. the higher position when the ground is very uneven,
. the lower position when the crop is short and light.
- Lengthways adjustment : This adjustment is made by moving swath screen either toward the front or toward
the rear (holes T), after first unscrewing the 2 attachment screws (F) (photo 10). When working in green forage,
it is recommended to move swath screen forward to catch any crop thrown sideways.
